UPDATE: I should have mentioned this earlier, but we're looking for reader questions for tonight's debate between Bruun and Schrader. Go ahead and post questions here and I will forward them along. The debate sponsored by The Oregonian and KGW will start at 7 p.m.

Here's an eye-popping poll from SurveyUSA that shows Republican challenger Scott Bruun with a 10-point lead over Democratic Rep. Kurt Schrader in Oregon's 5th Congressional District.

There's no doubt that Schrader is in real trouble. My only caveat is that I wonder about SurveyUSA's estimate of who will turn out in the election. The latest voter registration figures I've seen by congressional district - from September - shows Democrats with a five-point registration edge, 40.1 percent to 35.4 percent for Republicans.

Yet the SurveyUSA poll estimated turnout this way: 44 percent Republican, 37 percent Democrat and 18 percent other. Even though Republican turnout is likely to be higher than Democrats this year, that doesn't seem right to me.

Still, this ought to put a bigger spotlight on the race - just in time for tonight's big debate between Schrader and Bruun sponsored by The Oregonian and KGW. It will be carried live on KGW at 7 p.m. and yours truly will be one of the questioners.

One further point. The 5th District has long been seen as Oregon's biggest swing district, in part because voters there are seen as more conservative than the other two congressional districts that touch on the Portland area.
